DETAILED DESCRIPTION OF EXAMPLES OF EMBODIMENTS

This patent application describes, among other things, examples ofcertain embodiments, and certain aspects thereof. Other embodiments maydiffer from the particular examples described in detail herein. Variousembodiments are or include devices, apparatuses, machines, and methodsfor whitening teeth. In various embodiments, for example, light is usedto whiten teeth. In many embodiments, a chemical is (e.g., also) used towhiten the teeth. In a number of embodiments, the light, or heat fromthe light, accelerates the whitening gel, for example, inside a closedsystem or mouth piece. Further various embodiments result in faster,more efficient, or longer lasting whitening, or a combination thereof,for instance, without the sensitivity of certain alternatives. Severalexamples are described herein, and different embodiments include one ormore features from one or more of the examples described herein. Allworkable combinations are contemplated as different embodiments.

FIGS. 1 to 4 illustrate an example of an embodiment of a device or mouthpiece for whitening teeth, device or mouth piece 100. In thisembodiment, device 100 includes hand gesture control or sensor 105(e.g., shown in FIG. 1) and LEDs 210 (e.g., shown in FIG. 2). In thisembodiment, LEDs (light emitting diodes) 210 collectively form a lightsource that is located outside of the user's mouth when device 100 isproperly positioned for operation, which is partially within the user'smouth. Light from LEDs 210 reflects off of polished surface or reflector220 (e.g., shown in FIG. 2) to the user's teeth when device 100 is inoperation.

In some embodiments, LEDs (e.g., 210) emit blue light. In certainembodiments, for example, the blue light has a wavelength ofapproximately 470 nm (nanometers) and is part of the “visible lightspectrum”, which ranges from approximately 400 nm to 700 nm. In variousembodiments, the light (e.g., from LEDs 210) is harmless or has no knownnegative effect to the human body. Further, particular embodiments allowthe customer or user to use the device (e.g., 100) or method forless-lengthy whitening sessions compared to other systems. Even further,in various embodiments, the serum formula works in conjunction with thelight (e.g., from LEDs 210) to speed up whitening. Further still, insome embodiments, serum is refrigerated, for example, until delivered tocustomers, for instance, in warehouse facilities. This maintains thepotency of the chemical compounds in various embodiments.

As shown in FIGS. 3 and 4, in the embodiment illustrated, device ormouth piece 100 includes decorative front cover 401, decorative chromeband 402, wireless charging receiver PCB 403, motion detection lens 404,outer case 405, battery 406, LED sensors controls 407, gesturerecognition and BLE PCB 408, self-cleaning UV LEDs and RGBW sensors 409,main hub 410 (e.g., that supports the PCBs), activating LEDs 210, LEDreflector 220, clear LED water proof cover 411, and clear silicone mouthpiece 412. Clear silicone mouth piece 412 is shown in FIG. 1 but omittedin FIG. 2 to better illustrate other components.

Activating Light Reflector

Summary of Problem:

Prior designs of activating elements require a flexible PCB and lightelements within the mouth cavity. These source elements were fixed withno modulation schemes or intensity controls. In various embodiments,light (e.g., from LEDs 210 shown in FIGS. 2 to 4) is used to whitenteeth (e.g., in conjunction with chemical treatment). In a number ofembodiments, however, it is necessary or beneficial to avoid using toomuch light.

Solution:

In a number of embodiments, a light reflection system (e.g., LEDs 210and reflector 220) is controlled, for instance, via a pulse widthmodulation circuit (e.g., 808 shown in FIG. 8), for example, to controlthe grid and reflection pattern of a reflected light source (e.g., 210or 210 and 220). In some embodiments, light reflection patterns aredesigned to change the intensity of the light waveform, for instance, bymodifications to the peak output. Further, in particular embodiments,control mechanisms are done via wireless controls (e.g., Bluetooth),hand gestures (e.g., EMF—Electro-Magnetic Fields, IRF—Infrared Fields),or both. Still further, in certain embodiments, modulation schemes allowfor power schemes of 0-100%, for example. An example of a device isdevice 100 shown in FIGS. 1 to 4, for instance. FIG. 8 is a schematic orblock diagram showing how different electronic components are connectedto each other in certain embodiments. Other embodiments may differ. Notnecessarily every electrical connection or component is shown.

In various embodiments, the components of a reflector (e.g., 220)include a (e.g., chromed) reflective surface, for example, with anangled edge, for instance, to reflect light (e.g., from one or moreLEDs, for instance, 210). Further, some embodiments, for example,include a reflector PCB, for example, that reflects light to (e.g., eachof), for instance, six (6) quadrants of teeth. These quadrants may be,for example, in some embodiments: Center Top, Center Bottom, Left Top,Left Bottom, Right Top, and Right Bottom. In certain embodiments, the(e.g., LED) reflector PCB includes or consists of 6 arrays (e.g., ofLEDs, for instance, 210), for example, independently controlled, forinstance, to light each of the 6 quadrants. In turn, in someembodiments, the arrays or LEDs (e.g., 210) are driven, for example, byPWM (Pulse Width Modulation, e.g., 808), for instance, to alter theindividual light intensity (e.g., in each quadrant). Further, inparticular embodiments, the reflector (e.g., 220) is placed over a(e.g., flex) PCB.

In various embodiments, the reflector (e.g., 220) is made out ofpolished steel, chrome plating, or polished brass, as examples. Further,in a number of embodiments, the reflector (e.g., 220) is designed (e.g.,shaped) to reflect light from outside of the users mouth (e.g., fromLEDs 210), for example, evenly, for instance, throughout the center,left, and right sides of the user's mouth. In various embodiments, thelight source (e.g., 210) is external to the mouth (i.e., when mouthpiece 100 is properly positioned for treatment of the user's teeth) andthe reflector (e.g., 220) reflects and distributes the light within themouth. In a number of embodiments, this provides controlled distributionof the light, for example, in contrast with certain prior alternativesthat do not guide the light at all.

In a number of embodiments, the light source (e.g., 210) is or includesLEDs, for example, discrete, RGB (red, green, blue), or both, forinstance, which allows for variation in the frequency of the light insome embodiments. Further, an example of the pulse width modulationcircuit is shown in FIG. 8 (e.g., 808 or TLC59108, for instance,connected to the LED arrays, for example, 210). In contrast with pulsewidth modulation (e.g., 808), other alternatives are On/Off. In a numberof embodiments, the pulse width modulation circuit (e.g., 808) controlsthe grid and reflection pattern of the reflected light source (e.g.,210). In certain embodiments, for example, the PWM circuit (e.g., 808)works with the on-board intelligence of the mouth piece (e.g., 100).When the teeth are scanned, in some embodiments, an algorithm determines(e.g., based on the timer and shade value received for the quadrant),what duty cycle to set (e.g., for each quadrant), for instance, when thetreatment begins. Due to the flexibility of the modulation scheme, inparticular embodiments, the algorithm may be further tuned, for example,to generate modulation patterns to further enhance the treatmentprocess, for instance, by the dynamic variation of the duty cycles foreach quadrant. In certain embodiments, peak output (e.g., in terms ofmillicandela or mcd), or the intensity of light (e.g., from 210) ordynamic variations is controlled, for example, by the algorithm, drivenby the PWM (e.g., 808), or both.

Further, in a number of embodiments, wireless control serves as amechanism to utilize a third-party wireless device, for example, forsetup, control, additional algorithms for analysis and treatment, or acombination thereof. Still further, in some embodiments, hand gesturesare detected (e.g., via sensor 105) via electro-magnetic field (EMF) orinfrared (IR), for instance, array 805 shown in FIG. 8), as examples.With an EMF solution, for instance, multiple antennas are set up in anarray (e.g., sensor 105), in some embodiments, generating a field whichcan be manipulated by passing through the field with a hand or finger.In a number of embodiments, the antenna field is measured by thetransmitter, and when a change is detected, the logic analyzes thecondition. In various embodiments, for instance, the order of statechanges determines the gesture to be achieved. For example: in a twoantenna system (e.g., of sensor 105), if the left antenna triggered astate change, followed by the right antenna, the logic would assume thatsomeone was swiping from left to right. Further, in certain embodiments,an IR solution works (e.g., in a similar way) using an array of IRtransmitters (e.g., of sensor 105, for example, 805), for example, withan IR receiver centrally located within the array (e.g., 105 or 805).The example above also holds true for the IR solution (e.g., 805) insome embodiments. In a number of embodiments, hand gestures are read ordetected by or at a mouth piece (e.g., 100, for instance, via sensor105). Further, certain embodiments provide a simplified way to interactwith a smart connected device. In particular embodiments, however, useof an app is avoided.

Various embodiments are or include a device (e.g., 100) for whiteningteeth. Further, different embodiments include a light reflection system(e.g., light source 210 and reflector 220), a pulse width modulationcircuit (e.g., 808 shown in FIG. 8), or both. Still further, inparticular embodiments, the lighting system (e.g., 210) or lightreflection system (e.g., 210 and 220) is controlled, for example, by thepulse width modulation circuit (e.g., 808). Even further, variousembodiments include a reflected light source (e.g., 210 or 210 and 220).Moreover, in some embodiments, the pulse width modulation circuit (e.g.,808) controls a grid, a reflection pattern of the reflected lightsource, or both. Further still, in some embodiments, light reflectionpatterns are controlled, for instance, to change intensity of a lightwaveform, for example, by modifications to a peak output.

In various embodiments, a device (e.g., 100) for whitening teeth of auser includes a light source (e.g., 210) and a light delivery mechanism(e.g., reflector 220), for example, that delivers light from the lightsource (e.g., 210) to the user's teeth. In some such embodiments, forinstance, the light source (e.g., 210) is driven by a pulse widthmodulation circuit (e.g., 808 shown in FIG. 8). Further, in a number ofembodiments, the device (e.g., 100) includes a light source (e.g., 210)and a pulse width modulation circuit (e.g., 808) that drives the lightsource (e.g., 210). Still further, in various embodiments, the lightsource (e.g., 210) is located outside the user's mouth, the mechanism(e.g., reflector 220) that delivers light from the light source (e.g.,210) to the user's teeth is located within the user's mouth (i.e., whenthe device, e.g., 100, is in use), or both. Further still, in variousembodiments, the mechanism that delivers light from the light source(e.g., 210) to the user's teeth is a reflector (e.g., 220), the lightsource includes LED's (e.g., 210), or both. Even further, in particularembodiments, the light source (e.g., 210) includes multiple (e.g.,arrays of) light sources (e.g., 210), the multiple (e.g., arrays of)light sources are each independently controlled, the multiple (e.g.,arrays of) light sources (e.g., 210) are each driven by pulse widthmodulation (e.g., 808), or a combination thereof, for example. Evenfurther still, in some embodiments, the multiple (e.g., arrays of) lightsources (e.g., 210) each primarily illuminate a different quadrant ofthe user's mouth, intensity of the multiple (e.g., arrays of) lightsources (e.g., 210) is controlled, intensity of the light source (e.g.,210) is controlled (e.g., via PWM 808), or a combination thereof, asexamples.

In a number of embodiments, the light source (e.g., 210) illuminatesvarious (e.g., six) quadrants of the user's teeth. Further, in someembodiments, the light delivery mechanism (e.g., reflector 220) deliverslight (e.g., from the light source, for instance, 210) to (e.g., six)quadrants of the user's teeth. For example, in particular embodiments,the (e.g., six) quadrants of the user's teeth are or include: CenterTop, Center Bottom, Left Top, Left Bottom, Right Top, Right Bottom, or acombination thereof, as examples. Still further, in particularembodiments, the light delivery mechanism (e.g., 220) has an anglededge. Further still, in some embodiments, the device (e.g., 100) forwhitening teeth further includes a printed circuit board. Even further,in certain embodiments, the light delivery mechanism (e.g., 220) islocated over the printed circuit board, the printed circuit board isflexible, or both. Even further still, in particular embodiments, thelight delivery mechanism (e.g., 220) delivers light (e.g., substantiallyevenly) from the light source (e.g., 210) to the user's teeth. In thiscontext, “substantially” means to within plus or minus 25 percent.

In some embodiments, the light source (e.g., 210) is an RGB lightsource. Further, in some embodiments, the device (e.g., 100) iscontrolled wirelessly, for example, using a separate electronic device.For instance, in certain embodiments, the light source (e.g., 210), inparticular, is controlled wirelessly using a separate electronic device.Still further, in some embodiments, the device (e.g., 100) is controlledusing hand gestures (e.g., via sensor 105 shown in FIG. 1). Forinstance, in particular embodiments, the light source (e.g., 210) iscontrolled using hand gestures (e.g., detected by sensor 105). Evenfurther, in some embodiments, the device (e.g., 100) includes a gesturesensor (e.g., 105), for example, for sensing the hand gestures.

Visible Light Shade Detection System

Summary of Problem:

Until now, the accuracy of determining the color or shade of a user'steeth has been a manual process, using both personal observation andshade guides provided by the dental community.

Solution:

In various embodiments, the process of identifying the color or shade ofteeth is automated. Further, in a number of embodiments, accuracy isimproved over previous subjective methods in which color or shade was amatter of perspective. Still further, in various embodiments, (e.g.,high accuracy) color sensors (e.g., 230 shown in FIG. 2) are used. Insome embodiments, for example, these color sensors (e.g., 230) utilizered, green, blue, and white (RGBW) detection elements, as examples. Someembodiments are calibrated by using warm and cool colored white lightsources, for instance (e.g., LEDs 210 shown in FIG. 2). In variousembodiments, the sensors (e.g., 230) sense or analyze the reflectedlight from the target surface. In some embodiments, for example, thesensors (e.g., 230) sense color, while in other embodiments, the sensors(e.g., 230) sense shade, and in certain embodiments, the sensors (e.g.,230) sense both color and shade (e.g., of the teeth). Further, incertain embodiments, color or shade readings are output, for instance,over i2c, for example, in the value which references the visible lightspectrum (390-700 nm). In a number of embodiments, the data is injectedinto a learning algorithm, for instance, running on a Host processor.Still further. In particular embodiments, this Host processor, forexample, calculates the recommended treatment. Treatment settings forthe Activating element are automatically populated, in some embodiments,for instance, when the device (e.g., 100) is in autonomous mode. Evenfurther, in certain embodiments, the data is output wirelessly (e.g.,via Bluetooth), for example, connecting to an App, to the cloud (e.g.,for detailed analysis), or both.

In various embodiments, calibration cool and warm light source elements(e.g., LEDs 210 shown in FIG. 2) are used in the calibration of the(e.g., color) sensor (e.g., 230). In some embodiments, for example, thewarm and cool elements represent the color temperature of white light inthe frequency spectrum necessary to achieve an accurate measurement ofcolor. In particular embodiments, six (e.g., color) sensors (e.g., 230)are used, for example, in the locations shown. In some embodiments, RGBWsensors are used. Further, in some embodiments, six sensors (e.g., 230)translate to six individual grids, for example, three on top and threeon the bottom. In certain embodiments, for instance, the configurationis designed to assign multiple quadrants to the mouth for analysis. Invarious embodiments, for example, the more sensors (e.g., 230), the moreaccurate the measurements will become, for instance, within eachquadrant. In various embodiments, color data is collected from the teethand used to control a teeth-whitening process, for instance, using acomputer or a processor to analyze the color data. Further, particularembodiments use a computer or a processor to analyze the color data andcontrol a teeth-whitening process (e.g., using the output from thecomputer or processor). Even further, in a number of embodiments, the“reflected light” is light originating from the teeth-whitening device(e.g., 100, for instance, from LEDs 210).

Certain embodiments use a learning algorithm to analyze color data, forexample, to determine a treatment process. In a number of embodiments,for example, a recommended treatment includes, for example, anintensity, a duration, or both (e.g., of light emitted from LEDs 210).In various embodiments, the recommended treatment is different fordifferent teeth. In various embodiments, the recommended treatment iscalculated or determined, for example, based on compiled user data.Further, in some embodiments, a learning algorithm is used, for example,to allow the user to be hands off, let the hardware control thetreatments, or both. Other embodiments, however, do not use a learningalgorithm. Still further, different embodiments, use wireless or wiredcontrol, for example, of the hardware mechanisms.

Particular embodiments include, for example, sensor initialization,calibration, measurement, and data output. In some embodiments, analgorithm receives data output, calculates color, compares color to allquadrants, sets timer and peak intensity to each quadrant (e.g., basedon shade color and delta between quadrants), or a combination thereof.In some embodiments, for example, data is output from the sensors (e.g.,230) over i2c to the host processor. Further, in some embodiments, datais input into the learning algorithm over I2c, for example, from sensors(e.g., 230), the cloud, and a smart device, for instance, running anapplication. Still further, in particular embodiments, sensor data anduser data (e.g., from the cloud) is input into the learning algorithm.Examples include, in some embodiments, shade, color, serum strength,number of treatments per day, or a combination thereof. Even further, insome embodiments, feedback that is input into the learning algorithm toenable it to learn includes treatment times (e.g., in minutes),intensity, number of uses, shade data (e.g., at start of use to end ofuse), or a combination thereof. Even further still, in particularembodiments, output that is received from the learning algorithmincludes device settings for treatment cycles, for example, intensity,duration, notifications (e.g., in the app), or a combination thereof.Moreover, in certain embodiments, output is used for treatments,enhancing the algorithm, or both. In various embodiments, treatmentsettings are or include intensity, duration, or both (e.g., of eachquadrant).

Certain embodiments include a host processor, for example, a Master i2Ccontroller for peripherals. Further, particular embodiments include anactivating element, for example, blue LEDs (e.g., 210). Further still,in some embodiments, information is automatically populated, forexample, from the hardware or from the App. Even further, someembodiments include an autonomous mode, for example, that uses themachine learning, for instance, to set up the treatments. Still further,in some embodiments, other modes include gesture control, shake andwake, autonomous, wireless, or a combination thereof, as examples.

Self Cleaning Mouth Guard

Summary of Problem:

Prior designs in production offer a washable surface which leavesopportunities to grow bacteria and to cause infections within the user'smouth.

Solution:

In a number of embodiments, ultraviolet light sources, for example, areembedded within the mouth guard, for instance, to clean the mouth piecewhen the user has finished using the product. For example, FIG. 2 showsUV light source elements 240 located in device, mouth piece, or mouthguard 100. In FIG. 2, two UV light source elements 240 are visible, butin some embodiments, a third UV light source element is present oppositethe UV light source element 240 that is on the right side of FIG. 2. Insome embodiments, the UV light source elements (e.g., 240) shineultraviolet light on up to 100 percent of the mouth guard (e.g., 100) orthe portion of the surface of the mouth guard that is in the mouth ofthe user when in operation. In various embodiments, utilization of awireless charging system, and safety mechanisms to protect the usersfrom damaging their eyes during the clean cycle, require that the mouthguard (e.g., 100) be successfully docked in an enclosure and theenclosure cover closed. FIG. 5 shows an example of an enclosure,enclosure 500, with cover 501 closed. In some embodiments, for example,the enclosure (e.g., 500) has a shape of a circular cylinder (e.g., asshown, for instance, cylindrical body 510), for example, with flat ends(e.g., at top and bottom) that are perpendicular or substantiallyperpendicular to a centerline of the cylinder. FIG. 5 shows excess cablestorage 502, micro USB power connection 503, and cover hinge 505. FIG. 6shows enclosure 500 with cover 501 open and mouth piece 100 dockedinside enclosure 500 (e.g., for charging, sterilization, storage, or acombination thereof). In some embodiments, the cover (e.g., 501) hasembedded charging circuits and BLE, magnetic latching, or a combinationthereof, as examples. Further, FIG. 6 shows swing out serum wand andcable storage or swing door 660 (e.g., magnetic latching). In someinstances herein, the word “device” refers to the mouth piece (e.g.,100) only, but in other instances, the word “device” may include theenclosure (e.g., 500) or charger. Further still, in certain instances,the word “device” may include a computing device, for example, that isin communication with the mouth piece (e.g., 100). Still further, thesealternatives are not necessarily exhaustive.

In a number of embodiments, when the mouth piece (e.g., 100) has beensuccessfully docked (e.g., in enclosure 500, for instance, as shown inFIG. 6), and the enclosure cover (e.g., 501) closed (e.g., as shown inFIG. 5), Hall effect sensors, for example, on two sides of theenclosure, trigger or enable the wireless charging system. This is anexample of a safety mechanism that protects the user from eye damagefrom the ultraviolet light source. Once the transmitter has beenenabled, in some embodiments, wireless charging protocol begins totransmit to the receiver, for instance, first checking for foreignobjects in the path between the mouth guard (e.g., 100) and theenclosure (e.g., 500). In certain embodiments, once no objects aredetected and the receiver has acknowledged communication, a timer on thereceiver will trigger the UV elements (e.g., 240), for instance, for aparticular time (e.g., X.xxxmS), which is a programmable timer in someembodiments. In particular embodiments, the UV elements (e.g., 240) arepowered (e.g., directly) from the receiver side bridge and receiver, forinstance, which keeps the elements (e.g., 240) from turning onaccidently.

Various embodiments (e.g., of a teeth-whitening device, for instance,100) include one or more ultraviolet light sources (e.g., 240), forexample, LEDs, for instance, to clean (e.g., sterilize) theteeth-whitening device (e.g., mouth piece, for instance, 100). Further,in various embodiments, the “ultraviolet light sources” (e.g., 240) arelocated in the wireless charging system, are driven by the wirelesscharging system, operate (e.g., sterilize or apply UV) while chargingthe (e.g., teeth-whitening) device (e.g., 100), or a combinationthereof. Still further, certain embodiments include a safety mechanism,for example, to protect users from damaging their eyes during thecleaning cycle. Even further, particular embodiments, require that themouth guard (e.g., 100) be successfully docked in an enclosure (e.g.,500) or that the enclosure cover (e.g., 501) be closed, for example,before charging the device (e.g., mouth guard 100), emitting UV (e.g.,from UV lights 240), starting the cleaning cycle, or a combinationthereof. Further still, some embodiments use one or more Hall effectsensors, for example, to trigger or enable a wireless charging system, aUV system (e.g., UV lights 240), or a sterilization or cleaning system(e.g., UV lights 240), as examples. The drawings show examples. Indifferent embodiments, various wireless charging protocols are used.

Some embodiments include a receiver, for example, an Infineon solution.Further, certain embodiments check for foreign objects in the pathbetween the mouth guard (e.g., 100) and the enclosure (e.g., 500), forexample, by detecting heat changes, current, or both. Still further, insome embodiments, the receiver acknowledges communication using Qi. Evenfurther, some embodiments include a timer, for example, that controlsthe amount of time that the UV elements (e.g., 240) or cleaning systemis operated. In certain embodiments, the timer is adjustable, forinstance, from 1-30 minutes. Even further still, in particularembodiments, the timer is set automatically, for example, using machinelearning.

Further, in someembodiments, an ultraviolet light source (e.g., 240) sterilizes themouth piece (e.g., 100). Still further, in particular embodiments, thedevice or ultraviolet light source (e.g., 240) sterilizes the mouthpiece (e.g., 100) when the mouth piece (e.g., 100) is not in the user'smouth. Further still, in a number of embodiments, the device orultraviolet light source (e.g., 240) sterilizes the mouth piece (e.g.,100) when user has finished using the device (e.g., 100) for whiteningthe user's teeth, for example, when the mouth piece (e.g., 100) ischarging.

Mouth Detection

Summary of Problem:

Prior whitening systems are required to be plugged in or turned onbefore the device has been put into the user's mouth.

Solution:

Various embodiments include one or multiple sensors or arrays thatenable the function of the device (e.g., 100) once in the user's mouth.In some embodiments, for example, an EMF (Electro-Magnetic Field) Array(e.g., EMF field sensor or array 250 shown in FIG. 2) is placed (e.g.,at three points) around the mouth guard (e.g., 100). In someembodiments, for instance, this requires the device (e.g., 100) to be inthe mouth before operation. In addition, in particular embodiments, thearray (e.g., 250) is enabled by using a wake on pick up feature, forinstance, of an accelerometer (e.g., 811 shown in FIG. 8), to wake thedevice (e.g., 100) from a deep sleep. In some embodiments, hand gestures(e.g., detected via sensor 105) or the use of the App over a wireless(e.g., Bluetooth) connection begin the treatment cycle (e.g., operationof LEDs 210).

In prior whitening systems that were required to be plugged in or turnedon before the device has been put into the user's mouth, this was asimple way to power the device, but there was no: intelligence for theuser, modes of treatment, or a real sense of travel and portability, asexamples. In some embodiments, a user can put the device (e.g., 100) inher mouth and then turn it on or plug it in, but in particularembodiments, this may impact the results. In certain embodiments, forexample, the timer starts once the activating LEDs (e.g., 20) are on. Invarious embodiments, an electro-magnetic field (EMF) array (e.g., viaEMF field sensor or array 250 shown in FIG. 2) is used or included in ateeth-whitening device, for example, to detect whether the device (e.g.,100) is in someone's mouth. Further, in particular embodiments, thearray (e.g., 250) is enabled by using a wake on pick up feature or anaccelerometer (e.g., 811) to wake the device. In certain embodiments,for example, the accelerometer (e.g., 811) goes to an interrupt pin thatcan wake up the primary processor. In some embodiments, the device(e.g., 100) goes into a deep sleep, for example, an extremely lowcurrent state, for instance, to extend battery (e.g., 406 shown in FIGS.3 and 4) life. Still further, in various embodiments, hand gestures(e.g., detected by sensor 105) are used.
